2.4 GHz ISM-band transceiver — TxRx only, no MCU on die
The Texas Instruments CC2500RTKG3 is a single-chip 2.4 GHz transceiver designed for low-power wireless links in the ISM band. It is a TxRx Only device — there is no integrated microcontroller, so the host system must provide the protocol stack and SPI master. The part supports 2FSK, GFSK, MSK, and OOK modulation, making it flexible for proprietary protocols or simple point-to-point links. Sensitivity is rated at -104 dBm, and the maximum data rate is 500 kBaud.
Obsolete — plan for last-time-buy or substitute
No successor part is recorded in the available lifecycle data. For existing BOM lines, last-time-buy quantities or independent-distribution sourcing are the practical options.
Key specifications for the BOM decision
The -104 dBm sensitivity and +1 dBm output power define the link budget; range depends on obstacles and antenna gain.
